Enables you to supply any server data that can then be parsed on the client.
A CustomJSPropertiesEventHandler method to which custom processing is delegated.
In some instances, it is necessary to obtain server information on the client. The delegate method defined by the CustomJSProperties property enables you to declare temporary client properties. Once declared, a property can be accessed on the client.
To add new properties, use the parameter's CustomJSPropertiesEventArgs.Properties property, which represents a collection of property names and their values. The only requirement is that property names must begin with the 'cp' prefix, to avoid rewriting the base properties exposed by the NavBar extension.
